WALTER 1,757,154 TRIPLE HINGE INDEX UNIT Filed April 21 1925 2 Sheets-Sheet 2 d I I Moi/mu glwuntog Patented May 6, 19 30 UnITEo "STA nnw itn ctnxronwen'rnit, ceases, NEW saas m ass eaoe To 'rHE um- FISHER COMPANY, or new, YORK, n. Y.,- A canteen-miter DELAWARE T IPLE-HINGE -n'nnx UNIT Application filed April 21, 1925: Serial miaawej r This invention relates to cardindeiies of that type characterized by aseries of cards which are normally stored or nested in a card tray and adapted to be swung, individually or in series, to expose any'des'ired card. J'The object of the invention is to provide a plurality of cards with a swinging support, so arranged thatwhile all of the cards may be nested in the tray inth-eusual manner, a plurality of cards may be elevated from-the tray by the swinging of their supports and then individually swung to facilitate recording thereon, or the inspection 'Q'fa record already made on: either side of the individual card's.

To the accomplishment of the stated object, and others subordinate thereto, the pre-. ferred embodiment of the invention is illustrated in the accompanying drawings in V which Figure 1 is a longitudinal sectional View of a card tray showing a plurality ofcard units, one of which occupies its normal or stored position, and the other of which occupies an i p I,

1 through aslot 17 in the-board. If desired,

elevated position on a posting board. Figure 2 is a plan view of the same. Figure 2, is a plan view showing a modified form of posting board.

Figure 3 is a perspective view of one of the card units, and

' Figure a is another perspective view showing the cards elevated and swungin opposite directions to horizontal positions.

A. shallow tray 1 is provided at the bottom of its side walls with guideways 2 for the reception of the opposite ends of retaining portions 3 of a card index unit 4, which in this instance includes two record portions, cards, or leaves 5 and 6, connectedby independent hinges 7 and 8, with an intermediate portion 9, having hinge connection as at 10, with the retaining portion 3. 7

Usually, the leaves 5 and 6, instead of carrying the record directly, constitute card holders to which record cards 11 and 12 are detachably secured. The specific manner of attaching the cards to the holders constitutes no part of the present invention, but it 7 so is usual to slit at least one of the holders or leaves, as at Beadle; and to passthroug'h I these slits tabs 15 and 16, formed on the cards.

Whether or not the record is printed di rectly on the leaves 5'and 6, which thus constitute record cards, or on separate cards 11 and 12, carried by the leaves, is immaterial since in either event the index unit will' besee'nto embrace hinged record'p'ortionsor cards retained in the by a retaining'p'oi tion 3, through the me iumof a hinged intermediate portion 9' which may assume eithera horizontal or a Vertical'p'osition, to dispose the cards in either a depressed or elevated position as shown in Figures 3 and 4, for storage or recording.

The retaining portions of the adjacent indeX unitsare overlapped in the guide inthe tray tofacilitate the close nesting of the units so that alarge number thereofmay be stored in a small space, butflwhen'it'is de sired to enter a record axs'elec'ted index unit is raised to a vertical'positioii fro nithe hinge 10. andaslotted posting board 17 is mapped upon the tray with the cards extended this slot may be opened at one end as shown at 17 it; Figure 2? so that the board can be slippjedlaterally to itsposition; In any event; when the 'board has been located the, cards can be swung downthereon, eithei together or individiially, in either direction so that either face of either card may lie-inspected or posted. 7

From the foregoing the present invention may be cleatly understood, but the right to vary or modify the samewithin the scope of the protection granted is expressly reserved. What I claim is'i v 1;- The' combination with a guide, of an indexdevice engaging the guide and having an fiiX-lSOf movement adjacent said guide, saidfdevice including'a plurality of day, having a; u

record portins' mounted to s ace them from down over the posting board at opposite sides of the opening therein. V

I 3. The combination with a tray, having a guide, of aniindex unit including a retaining portionengaging the guide, a plurality of hinged. record portions, anintermediate portion Carrying the record portions, and

hinged to the retaining portion of the unit,

and a'posting board having anopening to accommodate the intermediate portion of the index unit.

l 4. The combination with a tray, of an index device having means forretaining it on the tray, said device being movable to swing as a unit relative to said-retaining means and tray, and including a plurality of record portions and means to mount them inspaced relation to the retaining means and with individual'swinging movement.

5. The combination with a tray, having a guide, of an index device including retaining hinged to the intermediate portion.

7. The combination'with atray, of a posting board having an opening and'adapted to rest upon said tray, and an index device including a retaining portion secured in the tray, an intermediate portion movable relative to the retaining portion to a position to allow it to project through the opening in the board, and a plurality of record portions carried by the intermediate portion and movable thereon to a position overlying the board.

8. An indexdevice for use with a tray have ing a guide, said device including a guide engaging portion, a plurality of record portions, and means connecting the record portions to said engagingportion andproviding for unitary swinging movement of the record portions about an axis spaced from said engaging portion and also providing forindependentswinging' movement} of the record portions about individual axes, v

9. Anindex device for use with a tray and including a retaining portion for securing the 7 device in the tray, a supporting portion hinged to the retaining portion, and a plurality of recording portions hinged at a common'point to the supporting portion of said device. V V

10. An index device for use with atray and including a retaining portion for securing the device in the tray, a supporting portion hinged to the retaining portion, and a p111 I rality of record portions spaced from the retaining portion by said supporting portion and-each hinged at one edge to'the supporting portion for individual swinging movement. i

11. The combination with a tray anda posting board adapted to rest thereon and to be moved thereon and having anopen-ended slot, of an index device including av retain ing portion for retaining the devicein the tray, a plurality of record portions, and an intermediate portion, the latter being hinged to the retaining portion tolallow it to assume means movable about an axis adjacent the bot tom of the tray to position the reco'rdportions in the tray for storage or above the posting board for recording operations thereon.
